Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to amino substituted steroids which are useful as pharmaceutical agents.

2. Description of the Related Art

Various amino (substituted) steroids are known with the amine substitution on either the steroidal ring system or on the side chain of the D-ring at C.sub.17.

U.S. Pat. No. 4,456,602 discloses steroidal 21-esters in which there is an amino function in the non-steroidal portion of the ester.

In the 3.alpha.-hydroxy series, U.S. Pat. No. 3,998,829 discloses 21-aminomethyl steroids and U.S. Pat. No. 3,983,111 discloses 21-amino steroids where the amino group is cyclized. These patents also disclose reduced A-ring steroids as well as steroids with a hydrogen atom at C.sub.17 and two hydrogen atoms at C.sub.11.

20-Amino steroids are known in the .DELTA..sup.4 -3-keto series with no substitution at C.sub.11 and C.sub.17, see Can. J. Chem., 47, 160 (1969); J. Med. Chem., 27, 1690 (1983); U.S. Pat. Nos. 4,377,584 and 4,191,759; Chem.-Biol. Interact., 46, 1 (1983); J. Steroid Biochem., 20, 1095 (1984); Inorg. Chim. Acta, 91, 257 (1984), with substitution at C.sub.11, see Steroids, 35, 265 (1980) and Biochim. Biophys. Acta, 623, 280 (1980) as well as with substitution at both C.sub.11 and C.sub.17, see Steroids, supra.

20-Amino steroids are known in the .DELTA..sup.1,4 -3-keto series with an 11.beta.-hydroxyl substitution, see Steroids, supra, as well as with 11.beta.,17.alpha.-dihydroxy substitution, see Protides Biol. Fluids, 29, 393 (1982); J. Clin. Chem. Clin. Biochem., 22, 209 (1984); Eur. J. Biochem., 108, 47 (1980); J. Steroid Biochem., 14, 697 (1981), Nature (London) 279, 158 (1979 ) and Eur. J. Biochem., 131, 333 (1983) and with 11.alpha.,17.alpha.-dihydroxy substitution, see J. Clin. Chem. Clin. Biochem., 21, 69 (1983). U.S. Pat. No. 4,191,759 discloses 20-amino.DELTA..sup.1,4 -3-keto steroids without any substitution at the 11 position where the amine substituent is morpholine or piperazine.

21-Amino steroids are known in the .DELTA..sup.4 -3-keto series with no substitution at C.sub.11, see J. Org. Chem., 45, 3084 (1980); J. Org. Chem., 26, 1223 and 5052 (1961); J. Chem., Soc., Perkin Trans. 1, 502 (1972); Great Britain Patent 954,146 and its U.S. equivalent, U.S. Pat. No. 3,123,598; Austrian Patent 249,883; Arch. Biochem. Biophys., 182, 197 (1977) and Khim.-Farm. 2, 26 (1968). In addition 21-amino steroids are known in the .DELTA..sup.1,4 -3-keto series substituted with 11.beta.-hydroxyl, see Arch. Biochem. Biophys., 182, 197 (1977); Int. Conf. Chem. Biotechnol. Biol. Act. Nat. Prod. 2, 135-49 (1981); Analyst (London) 98, 519 (1972); U.S. Pat. Nos. 3,705,150, 4,076,737 and 2,920,999; Nature, 191, 607 (1961); Hungarian Patent 150,350 and J. Org. Chem., 45, 3084 (1980). For example Hungarian Patent 150,350 discloses dipersolone, 11.beta.,17.alpha.-dihydroxy-21-(4-methyl-1-piperazinyl)pregna-1,4-diene-3 ,20-dione. Further, U.S. Pat. No. 3,705,150 discloses 21-[N-(N'-methyl)piperazinyl]prednisolone.

German Patent 1,087,598 and U.S. Pat. No. 2,920,999 disclose simple 21-amino derivatives of .DELTA..sup.4 -3-keto steroids. The amines include both mono and bis substituted amines. In the cases where the amino group is disubstituted, the two substituents can be cyclized with the attached nitrogen atom to form a heterocyclic amino group (morpholine, pyrrolidine, piperidine, pyridine). The amines where chosen from the group consisting of amino, monoalkylamino, dialkylamino, phenylamino, pyridylamino, benzylamino, picolinylamino, N-alkyl-N-phenylamino, N-alkyl-N-pyridylamino, morpholinyl, pyrryl, pyrrolidyl, piperidino and C-alkylated piperidino, though only N-piperidino, N,N-diethyl and N-methyl-N-phenyl were exemplified. The amino steroids of the present invention while containing the steroid portion of the compounds of U.S. Pat. No. 2,920,999, contain more complex amines.

U.S. Pat. No. 3,144,446 discloses mono and bis quaternary ammonium salts of triethylenediamine. The amines and amino steroids of the present invention do not include triethylenediamine or other bridged amine, only 1-piperazinyl substituted amines.

U.S. Pat. No. 2,665,274 discloses pyridium salts of steroids. In the present invention R.sub.21 and R.sub.210 are taken together with the attached carbon atom to form a heterocyclic ring but not an aromatic ring.

Chem. Abst. 70, 115402v (1969) discloses amino steroids where the amines are morpholino, piperidino and dimethyl. The amines of the amino steroids of the present invention are much more complex than these three simple unsubstituted amines.

A number of 20-amino steroids are known where the 20-amino group is of the general type --NH--(CH.sub.2).sub.x --N(R.sub.1)(R.sub.2) where x is 2 or 3 and R.sub.1 and R.sub.2 are methyl or ethyl. See, for example, Arch. Farmacol. Toxicol. 4, 265 (1978), Lipids, 2, 5 (1967), J. Med. Chem. 15, 1129 (1972), ibid 15, 1284 (1972), French Patent 90805, Lipids 11, 616 (1976), U.S. Pat. No. 3,558,608, Chem. Abst. 62, 14784a, ibid 64, 14573e, ibid 65, 2334d, ibid 56, 15583a, b, and i, ibid 57, 12574d, ibid 57, 6625d.

Many 20-amino and 21-amino steroids are known where the amino group is substituted with simple alkyl (C.sub.1 -C.sub.3), aryl (phenyl), simple aralkyl (benzyl), as well as substituents containing hetero atoms (sulfur), esters, acids, amino substituted alkyl, alcohols, ethynyl groups, etc. The amino steroids are known where the amino portion is either mono or disubstituted. In the cases where the amino group is disubstituted, the two substituents can be cyclized with the attached nitrogen atom to form a heterocyclic amino group. These simple cyclic and heterocyclic amines, see U.S. Pat. Nos. 3,523,942, 4,191,759 and 2,920,999, are unlike the complex amine substituents of the present invention. The known 21-amino substituted steroids include simple (substituted) cyclic amines such as 4-(2-hydroxyethyl)-1-piperazinyl [CA 65;20189g]; 4-(2-hydroxyethyl)-1-piperidinyl [83544-11-0]; 4,4-dimethyl-1-piperazinyl, 3-hydroxyethyl-1-piperidinyl, 4-hydroxy-1-piperidinyl, 4-carboxy-1-piperidinyl, 3-hydroxy-1-piperidinyl, 3-carboxy-1-piperidinyl, piperazinyl, bis(hydroxyethyl)amino, 4-acetyl-1-piperazinyl, 4-carboxaldehyde-1-piperazinyl, 1-piperidinyl, [Int. Conf. Chem. Biotechnol. Biol. Act. Nat. Prod. [Proc.]1st. Vol. 2, p. 135, 1981]; 4-methyl-1-piperazinyl [Great Britain Patent 2,136,293]; 3,6-dihydro-2,6-dioxo-1(2H)-pyrimidinyl, 5-fluoro-3,6-dihydro-2,6-dioxo-1(2H)-pyrimidinyl, 5-fluoro-3,4-dihydro-2,4-dioxo-1(2H)-pyrimidinyl, 3,4-dihydro-2,4-dioxo-1(2H)-pyrimidinyl, 3,4-dihydro-5-methyl-2,4-dioxo-1(2H)-pyrimidinyl [J. Steroid Biochem. 9, 1155 (1978)]; and 4-morpholinyl [J. Chem. Soc. Perkin Trans I, 502 (1972)]. The 4-methyl-1-piperazinyl group is a common substituent at the C.sub.21 position, see for example Int. Conf. Chem. Biotechnol. Biol. Act. Nat. Prod., 2, 135-49 (1981) [English] at Budapest, Hungary as abstracted in Chemical Abstracts 97(21), 182,723w (1982) which discloses various antiinflammatory 21-amino prednisolones such as 11.beta.,17.alpha.-dihydroxy-21-[4-methyl-1 -piperazinyl]pregna-1,4-diene-3,20-dione, DE 2,123,555 as abstracted in Chemical Abstracts 76(11), 59893r (1972) which discloses 11.beta.,17.alpha.-dihydroxy-21-[4-methyl-1-piperazinyl]pregna-1,4-diene-3 ,20-dione as being useful in the treatment of anaphylactic shock, Acta Pharm. Hung., 37(3) 97-107 (1967) as abstracted in Chemical Abstracts 67(12) 57273d (1967) which discloses 11.beta.,17.alpha.-dihydroxy-21-[4-methyl-1-piperazinyl]pregna-1,4-diene,3 ,20-dione and Khim.-Farm. Zh., 2(11), 26-9 (1968) as abstracted in Chemical Abstracts 70, 115402v (1969) page 380 which discloses 17.alpha.-hydroxy-21-[4-methyl-1-piperazinyl]pregn-4-ene-3,20-dione as well as the 21-morpholino steroid.

U.S. Pat. No. 3,697,509 discloses .DELTA..sup.17(20) -21-quaternary amino steroid salts. The .DELTA..sup.17(20) -21-amino steroids (V) of the present invention include pharmaceutically acceptable salts, but not quaternary amine salts.

Japanese published application J8 5043068 discloses azepino(1,2,3-1H)-.beta.-carboline derivatives which inhibit lipid peroxidation and are useful in inhibiting the aging of living bodies.

Some of the free amines of the amino substituent of the amino substituted steroids (XI) of the present invention are known. See, for example, U.S. Pat. No. 4,492,696.

U.S. Pat. No. 3,146,234 (ARCHER) discloses 1-[(1-, 2- and 3-indolyl)-substituted piperazines which have anticonvulsant activity, which can be depicted as 1-, 2- or 3-indolinyl]-[alkyl].sub.0-6 -PIPERAZINE-X.sub.2.

No. 4,409,223], 4-(3,6-dimethylpyrazinyl)piperazine [Canadian Patent 979,894], 4-(2-methoxy-phenyl)piperazine [Aldrich, item M2,260-1], 4-(4-methoxyphenyl)-piperazine [Aldrich item M2,300-4], 4-[(3,4-dimethoxyphenyl)methyl]piperazine [French Patent 7031 M], 4-(4-fluorophenyl)piperazine [Aldrich, item 19,133-7], 4-[[4(dimethylamino)phenyl]methyl]piperazine [U.S. Pat. No. 4,421,753], 4-hydroxy-4-[4-(trifluoromethyl)phenyl]piperazine [U.S. Pat. No. 3,936,464], (2-diethylaminoethyl)amine [Aldrich, item 12,694-2], [2-(3,4-dimethoxyphenyl)ethyl]amine [ Aldrich, item D13,620-4], [2-(2,4-dimethoxyphenyl)-1-methylethyl]amine [J. Pharm. Sci. 60, 1232 (1971)], [2-(3,4-dimethoxyphenyl)ethyl][[4-dimethylamino)phenyl]methyl]amine [Chem. Abst. 65:7001f] and (2-pyridinyl)methylamine [Aldrich, item A6,520-4], most are novel.

One of the amines of the present invention is 4-(2-furanylcarbonyl)piperazine, see PREPARATION A-3. The amine of the present invention differs from the prior art amine in that it does not have a cyano group and does not have a carbonyl group between the piperazine and the furoyl substituent.

Chem. Abst. 85, 78082c (1976) discloses 4-(2-furoyl)piperazine, 4-(2-thienyl)piperazine and 4-(3-thienyl)piperazine. The present invention includes 4-(2-furanylcarbonyl)piperazine, see PREPARATION A-3.

DETAILED DESCRIPTION OF THE INVENTION

The invention is amino substituted steroids (XI), namely the amino steroids (Ia and Ib), aromatic steroids (II), .DELTA..sup.16 -steroids (IIIa and IIIb), reduced A/B-ring steroids (IV) and .DELTA..sup.17(20) -steroids (Va and Vb) as well as the .DELTA..sup.9(11) -steroids (VI). Also included are the novel amine and steroidal reactants used to prepare the amino substituted steroids (XI), see PREPARATIONS "A" (amines) and "S" (steroids) respectively.

With the aromatic steroids (II) the A-ring functionality at C.sub.3 is a hydroxy group or substituted hydroxy group (ether or ester). However, with the amino steroids (Ia and Ib), .DELTA..sup.16 -steroids (IIIa and IIIb), reduced A/B-ring steroids (IV), .DELTA..sup.17(20) -steroids (Va and Vb) and .DELTA..sup.9(11) -steroids (VI) the A-ring functionality at C.sub.3 is either hydroxyl or ketone. When the A-ring functionality at C.sub.3 is hydroxy, the hydroxyl group can be in either the .alpha. or .beta. configuration. When the A-ring functionality at C.sub.3 is hydroxy, there will be either a reduced A/B-ring .DELTA..sup.4 or .DELTA..sup.5 double bond present but no double bond at C.sub.1 for the steroids of formulas (Ia, Ib, IIIa, IIIb, Va, Vb and VI). When the A-ring functionality at C.sub.3 is a ketone, then there will be a reduced A/B-ring or a .DELTA..sup.4 double bond present and no .DELTA..sup.5 double bond or there will be a .DELTA..sup.1,4 -diene A-ring functionality. The reduced A/B-ring steroids of formula (IV) have no double bond in either rings A or B and have at C.sub.3 either a hydroxyl group or a ketone.

The amino substituted steroids (XI) and .DELTA..sup.9(11) -steroids (VI) of the present invention are prepared by methods known to those skilled in the art from steroidal and amine reactants which are either known to those skilled in the art or which are readily prepared from compounds known to those skilled in the art by methods known to those skilled in the art.

When n is 0, the amino substituted steroids (XI) are amides and are produced in a preferred process by starting with the acid (--COOH at C.sub.17) and reacting it first with a condensing reagent such as carbonyldiimidazole or DCC in the presence of HOBT, followed by reaction with the free amine corresponding to the desired amine substituent as is known to those skilled in the art, see for example U.S. Pat. No. 4,438,130; see also EXAMPLES 56, 57 AND 103. The amine starting materials are either known to those skilled in the art or are readily prepared from compounds known to those skilled in the art by methods known to those skilled in the art. Suitable solvents include, acetonitrile, DMF, dioxane, THF, methylene chloride, and mixtures thereof.

When n is 1 through 6, the amino substituted steroids (XI) and the .DELTA..sup.9(11) -steroids (VI) are produced in a preferred process by reacting a steroid corresponding to the desired amino steroid (Ia and Ib), aromatic steroid (II), .DELTA..sup.16 -steroid (IIIa and IIIb), reduced A/B-ring steroid (IV), .DELTA..sup.17(20) -steroid (Va and Vb) and the .DELTA..sup.9(11) steroid (VI) but having a substituent at the terminal carbon atom, at C.sub.21 (n=1) through C.sub.26 (n=6), such as a halogen atom (chlorine, bromine or iodine), a mesyl or tosyl group, with the desired amine in an aprotic solvent (DMF, THF, methylene chloride, acetonitrile, DMA, ether) containing a base (carbonate, bicarbonate, triethylamine, diisopropylethylamine) as is known to those skilled in the art for the formation of amines. When n is 1, the C.sub.21 -halo, mesyl or tosyl substituted steroids are known to those skilled in the art or are readily prepared from compounds known to those skilled in the art by methods known to those skilled in the art. It is preferred that the halo substituent be a bromine atom but an iodine or chlorine atom is suitable. When n is 2 through 6, the halo, mesyl or tosyl substituted steroid is prepared by reacting the corresponding 17.beta.-carboxylate ester, of the desired steroid, with an organometallic reagent of the formula Li(CH.sub.2).sub.n --OR to form an intermediate with the desired C.sub.17 carbon side-chain length, followed by displacement of "OR" with the desired leaving group, see PREPARATION S-42.

The derivatives of the 3(.alpha./.beta.)-hydroxy steroids are prepared by methods known to those skilled in the art. When the 3-hydroxy steroid starting materials contain other free hydroxy or amino functionality these groups must be protected as is known to those skilled in the art. The free hydroxy groups are protected, for example, as the THP derivatives and the free amino groups are protected, for example, as the t-butyloxycarbonyl derivatives. The 3-O-acyl derivatives (steroid-O--COR) are prepared by first dissolving the 3-hydroxy compound in a solvent such as pyridine or methylene chloride and with a base such as triethylamine present. The mixture is cooled in an ice bath and treated with an acylating agent such as acetyl chloride, acetic anhydride, propionyl chloride, benzoyl chloride, etc. The reaction mixture is then partitioned between an organic solvent such as methylene chloride and aqueous bicarbonate. The organic phase is separated, dried, concentrated and purified, for example by chromatography. Likewise, 3-carbonates are produced by reacting the 3-hydroxy steroid with a reagent such as RO--CO--Cl.

The .DELTA..sup.4,6 and .DELTA..sup.1,4,6 derivatives are prepared by reacting the corresponding .DELTA..sup.4 starting material with a reagent such as chloranil following the general procedure of Campbell and Babcock, J. Am. Chem. Soc. 81, 4069 (1959). If a .DELTA..sup.1,4,6 derivative is desired, the .DELTA..sup.1 double bond is subsequently added by methods well known to those skilled in the art such as by fermentation or with DDQ.

When the substituent at C.sub.17.alpha. is a methyl or ethyl group and the substituents at C.sub.16 are hydrogen atoms, the compounds are prepared by first treating the corresponding .DELTA..sup.16 -steroid with lithium in liquid ammonia and then trapping the enolate with methyl or ethyl iodide. During this methylation the A-ring must be protected as is known to those skilled in the art. When the substituent at C.sub.16.alpha. is a methyl group and at C.sub.168 is a --H, the compounds are prepared by first adding methyl magnesium chloride in the presence of a copper propionate and trapping the enolate with methyl or ethyl iodide.

Alternatively, in principle, a form of the steroid not necessarily desired as the final product (XI), can be reacted in its C.sub.terminal form, for example when n is 1, 21-halo, 21-mesyl or 21-tosyl form with the appropriate amine to form a 21-amino steroid. Following this, the steroid nucleus itself can be modified. While this is an alternative process, in principle, to produce the amino substituted steroids (XI), of the present invention, in practice it is an undesirable method compared to the preferred process of reacting the C.sub.terminal halo, tosyl or mesyl analog corresponding to the steroidal portion of desired amino substituted steroids (XI), with the amine corresponding to the amine portion of the desired amino substituted steroids (XI) as is apparent to one skilled in the art--with the exception of the esters of the 11.alpha.-hydroxy steroids, see EXAMPLES 28, 31 AND 32.

Yet another alternative procedure, in principle, to produce some of the steroids of the invention involving amino substituents which can be thought of as having 2 or more components, can be produced by first reacting the 21-halo, tosyl or mesyl steroid with a portion of the desired amine substituent to form a steroid in which there is an amine substituent at the 21-position followed by further reaction of the amino portion of the amino substituted steroid to produced the complete substituent at the 21-position. For some steroids of this invention (EXAMPLES 9 and 10) this method is preferable, but as stated above for the other alternative procedure, while this is an alternative process in principle, in practice it is usually undesirable compared to the preferred process.

For the amino substituted steroids (XI), it is preferred that the steroid be the amino steroid (Ia and Ib), more preferably the amino steroid (Ia). It is preferred that the A-ring be .DELTA..sup.4 -3-keto or .DELTA..sup.1,4 -3-keto. At C.sub.6, it is preferred that R.sub.61, R.sub.65 and R.sub.67 be --H and R.sub.62, R.sub.66 and R.sub.68 be --H or --CH.sub.3. It is preferred that R.sub.7 be .alpha.-H:.beta.-H. For the C-ring it is preferred that R.sub.9 be --H or the C-ring be .DELTA..sup.9(11), more preferably .DELTA..sup.9(11). It is preferred that the substituent(s) at C.sub.16 be --H if there is only one substituent, or if two substituents, either two --H's or a --H and --CH.sub.3. If --CH.sub.3 it is preferred that it be in the .alpha. configuration. It is preferred that R.sub.175 be a --H, --OH, C.sub.2 -C.sub.7 alkanoyloxy or --O-- CO--X.sub.1 ; it is more preferred that R.sub.175 be --H. With regard to the side chain at C.sub.17, it is preferred that it be --C(.dbd.Z)--(CH.sub.2).sub.n NR.sub.21 R.sub.210. It is preferred that Z be .dbd.O. It is preferred that n be 1. Regarding R.sub.21 and R.sub.210 it is preferred that R.sub.21 and R.sub.210 are taken together with the attached nitrogen atom to form a cyclic amino substituent selected from 1-piperazinyl substituted in the 4- position with X.sub.2 --(CH.sub.2).sub.j -- [E] and 1-piperazinyl substituted in the 4-position with X.sub.1 --(CH.sub.2).sub.j -- [F]. It is preferred that j be 0.

It is preferred that the compounds not be the N-oxide. With the substituent [F], it is preferred that X.sub.1 be phenyl optionally substituted with 1,2 or 3 methoxy groups.

The amino substituted steroids (XI) and the .DELTA..sup.9(11) steroids (VI) of the present invention are reacted with acids to form amine salts by methods known to those skilled in the art and the resulting salts are more water soluble and therefore preferable to use when an aqueous formulation is desired such as a solution for IV use. Generally the amino substituted steroids (XI) and the .DELTA..sup.9(11) steroids (VI) possess one or more basic nitrogen atoms to be converted to an acid addition pharmaceutically acceptable salt. However, when n is 0 and Z is .dbd.O (i.e. amides) and the compound does not contain another nitrogen atom, they will not form satls suitable as pharmaceuticals. The pharmaceutically acceptable salt forms of the amino substituted steroids (XI and VI) are generally preferred over the free base form since the salts have greater water solubility and form crystals more suitable for pharmaceutical purposes. An acid addition salt of the amino substituted steroids (XI) and the .DELTA..sup.9(11) steroids (VI) can be converted to the free base, which can be converted to any desired pharmaceutically acceptable acid addition salt by methods known to those skilled in the art. It is preferred that the acid addition salt be prepared by reacting the free base of the amino substituted steroids (XI) and the .DELTA..sup.9(11) steroids (VI) with an approximately stoichiometric amount of an acid, such as hydrochloric, hydrobromic, hydroiodic, sulfuric, phosphoric, acetic, lactic, citric, succinic, benzoic, salicylic, pamoic, cyclohexanesulfamic, methanesulfonic, naphthalenesulfonic, p-toluenesulfonic, maleic, fumaric, oxalic acid and the like. It is preferred that the acid be selected from the group consisting of hydrochloric, maleic, methanesulfonic and fumaric acids.

The amino substituted steroids (XI) and the .DELTA..sup.9(11) steroids (VI) and acid addition salts can be isolated as hydrates or solvates, and such forms are regarded as equivalent to the corresponding amino substituted steroids (XI) and the .DELTA..sup.9(11) steroids (VI) not containing water or solvent.

The amino substituted steroids (XI) and the .DELTA..sup.9(11) steroids (VI) of the present invention are useful pharmaceutical agents in treating a number of different medical conditions in humans and useful warm blooded animals.

In humans, the amino substituted steroids (XI) and the .DELTA..sup.9(11) steroids (VI) of the present invention are useful in treating spinal trauma, mild and/or moderate to severe head injury,

Generally, the amino substituted steroids (XI) and the .DELTA..sup.9(11) steroids (VI) are useful in the same way as glucocorticoid pharmaceuticals for the treatment of the above human conditions as well as the animal conditions listed below. While the amino substituted steroids (XI) and the .DELTA..sup.9(11) steroids (VI) are useful in both humans and animals in treating many of the same conditions and preventing damage from the same problems as the glucocorticoids, the amino substituted steroids (XI) and the .DELTA..sup.9(11) steroids (VI) are useful in treating a number of conditions and preventing damage from conditions where the glucocorticoids are not useful. The amino substituted steroids (XI) and the .DELTA..sup.9(11) steroids (VI) have diminished glucocorticoid activity and therefore, unlike the glucocorticoids, they can be given daily for long periods of time (used chronically) without the side effects associated with the glucocorticoids. This is a distinct advantage.

It is to be understood that each of the amino substituted steroids (XI) and the .DELTA..sup.9(11) steroids (VI) is useful for a number of the above conditions but not each and every compound is useful for each and every condition. It is well within the ability of those skilled in the art to easily determine which particular amino substituted steroids (XI) and the .DELTA..sup.9(11) steroids (VI) are useful for each particular condition without undue experimentation. For example, the arachidonic acid LD.sub.50 test of Kohler, Thrombosis Res., 9, 67 (1976), identifies compounds which are antioxidants, which inhibit lipid peroxidation, and/or which inhibit the prostagladin cascade and are useful in treating spinal trauma, mild and/or moderate to severe head injury, degenerative neurological disorders, etc. Another method useful for determining which particular compounds inhibit lipid peroxidation and which are therefore useful in treating spinal trauma, mild, and/or moderate to severe head injury, degenerative neurological disorders, etc is descibed by Pryor in Methods of Enzymology 105, 293 (1984). Further, the mouse head injury assay of Hall, J. Neurosurg., 62, 882 (1980) discloses an assay from which one skilled in the art can readily determine which particular amino substituted steroids (XI) and the .DELTA..sup.9(11) steroids (VI) are useful in the acute treatment of spinal trauma or mild and/or moderate to severe head injury.

The standard conditions for treatment are to give the amino substituted steroids (XI) and the .DELTA..sup.9(11) steroids (VI) orally or parenterally, e.g. IV (that is by injection, infusion or continuous drip) or IM, with a standard dose of about 0.05 to about 100 mg/kg/day, one to four times daily.

For a number of the conditions to be treated with the amino substituted steroids (XI) and .DELTA..sup.9(11) steroids (VI) the preferred route of administration is parenteral. When certain of the amino substituted steroids (XI) are administered IV, hemolysis occurs in test animals. To prevent hemolysis it is preferred to use the following formulation: amino substituted steroid (XI) 1.5 mg/ml, citric acid-hydrate 20 mM, sodium citrate-dihydrate 3.2 mM, sodium chloride 4.5 mg/ml, pH=3.0, osmolality 183 mOsm/kg. The solution is prepared by first dissolving the amino substituted steroid (XI) in acidic media then adding the other excipients. After dilution with water to the final volume, the solution is sterilized by filtering thru a 0.22 .mu.m cartridge or disc and filled into sterile vials. The vials are stored at 4' to maintain stability.

Typical treatment will involve an initial loading dose, e.g. and IV dose of 0.01 mg to 1 mg/kg followed by maintenance dosing e.g. IV fusion for a day to a week depending on the particular condition of the patient and the particular compound used. This may be supplemented with IM or oral dosing for days, weeks or months to prevent delayed neuronal degeneration in neurological applications (e.g. spinal trauma, head injury).

In treating subarachnoid hemorrhage (thromboembolic) stroke the standard conditions are used and patients at risk are pre-treated orally.

In dogs, the amino substituted steroids (XI) and the .DELTA..sup.9(11) steroids (VI) are useful in treating head and spinal trauma, intervertebral diseases (slipped disk), traumatic shock, flea bite and other allergies.

In horses, the amino substituted steroids (XI) and the .DELTA..sup.9(11) steroids (VI) are useful in treating endotoxic or septic shock which follows colic, pretreatment before surgery for colic and treatment of Founder (laminitis).

In cattle, he amino substituted steroids (XI) and the .DELTA..sup.9(11) steroids (VI) are useful in treating acute coliform mastitis, bovine mastitis and acute allergic reaction to feed lot vaccination.

In pigs, the amino substituted steroids (XI) and the .DELTA..sup.9(11) steroids (VI) are useful in treating porcine stress syndrome and thermal stress syndrome.

The term treatment or treating as used in this patent is used broadly and includes both treatment of an existing condition as well as preventing the same condition from occurring where such is possible as is well known to those skilled in the art. For example, the amino substituted steroids (XI) and the .DELTA..sup.9(11) steroids (V) can be used to treat existing asthma conditions and to prevent future ones from occurring. For example, the amino substituted steroids (XI) and the .DELTA..sup.9(11) steroids (VI) treat spinal trauma and prevent rejection of skin grafts.

The exact dosage and frequency of administration depends on the particular amino substituted steroids (XI) and the .DELTA..sup.9(11) steroids (VI) used, the particular condition being treated, the severity of the condition being treated, the age, weight, general physical condition of the particular patient, other medication the individual may be taking as is well known to those skilled in the art and can be more accurately determined by measuring the blood level or concentration of the amino steroid (I), aromatic steroid (II), .DELTA..sup.16 -steroid (III), reduced A/B-ring steroid (IV), .DELTA..sup.17(20) -steroid (V) and .DELTA..sup.9(11) -steroid (VI) in the patient's blood and/or the patients response to the particular condition being treated.

DEFINITIONS AND CONVENTIONS

The definitions and explanations below are for the terms as used throughout this entire document including both the specification and the claims.

I. CONVENTIONS FOR FORMULAS AND DEFINITIONS OF VARIABLES

The chemical formulas representing various compounds or molecular fragments in the specification and claims may contain variable substituents in addition to expressly defined structural features. These variable substituents are identified by a letter or a letter followed by a numerical subscript, for example, "Z" or "R.sub.i " where "i" is an integer. These variable substituents are either monovalent or bivalent, that is represent a group attached to the formula by one or two chemical bonds. For example, a group Z would represent a bivalent variable if attached to the formula CH.sub.3 --C(.dbd.Z)H. Groups R.sub.i and R.sub.j would represent monovalent variable substituents if attached to the formula CH.sub.3 --CH.sub.2 --C(R.sub.i)R.sub.j)H.sub.2. When chemical formulas are drawn in a linear fashion, such as those above, variable substituents contained in parentheses are bonded to the atom immediately to the left of the variable substituent enclosed in parenthesis. When two or more consecutive variable substituents are enclosed in parentheses, each of the consecutive variable substituents is bonded to the immediately preceding atom to the left which is not enclosed in parentheses. Thus, in the formula above, both R.sub.i and R.sub.j are bonded to the preceding carbon atom. Also, for any molecule with an established system of carbon atom numbering, such as steroids, these carbon atoms are designated as C.sub.i, where "i" is the integer corresponding to the carbon atom number. For example, C.sub.6 represents the 6 position or carbon atom number in the steroid nucleus as traditionally designated by those skilled in the art of steroid chemistry. Likewise the term "R.sub.6 " represents a variable substituent (either monovalent or bivalent) at the C.sub.6 position.

Chemical formulas or portions thereof drawn in a linear fashion represent atoms in a linear chain. The symbol "--" in general represents a bond between two atoms in the chain, more specifically it represents a carbon-carbon bond. Thus CH.sub.3 --O--CH.sub.2 --C(R.sub.i)H--CH.sub.3 represents a 2-substituted-1-methoxypropane compound. In a similar fashion, the symbol ".dbd." represents a double bond, e.g., CH.sub.2 .dbd.C(R.sub.i)--O--CH.sub.3, and the symbol ".tbd." represents a triple bond, e.g., HC.tbd.C--CH(R.sub.i)--CH.sub.2 --CH.sub.3. Carbonyl groups are represented in either one of two ways: --CO-- or --C(.dbd.O)--, with the former being preferred for simplicity.

Chemical formulas of cyclic (ring) compounds or molecular fragments can be represented in a linear fashion. Thus, the compound 4-chloro-2-methylpyridine can be represented in linear fashion by N*.dbd.C(CH.sub.3)--CH.dbd.CCl--CH.dbd.C*H with the convention that the atoms marked with an asterisk (*) are bonded to each other resulting in the formation of a ring. Likewise, the cyclic molecular fragment, 4-(ethyl)-1-piperazinyl can be represented by --N*--(CH.sub.2).sub.2 13 N(C.sub.2 H.sub.5)--CH.sub.2 --C*H.sub.2.

A cyclic (ring) structure for any compound herein defines an orientation with respect to the plane of the ring for substituents attached to each carbon atom of the cyclic compound. In formulas depicting sch compounds, a substituent attached to a carbon atom below the plane of the ring is identified as being in the alpha (.alpha.) configuration and is indicated by a broken, dashed or dotted line attachment to the carbon atom, i.e., by the symbol "- - -" or "...". The corresponding substituent attached above the plane of the ring is identified as being in the beta (.beta.) configuration. When a variable substituent is bivalent, the valences may be taken together or separately or both in the definition of the variable. For example, a variable R.sub.i attached to a carbon atom as --C(.dbd.R.sub.i)-- might be bivalent and be defined as oxo or keto (thus forming a carbonyl group (--CO--) or as two separately attached monovalent variable substituents .alpha.-R.sub.ij and .beta.-R.sub.ik. When a bivalent variable, R.sub.i, is defined to consist of two monovalent variable substituents, the convention used to define the bivalent variable is of the form ".alpha.-R.sub.ij :.beta.-R.sub.ik " or some variant thereof. In such a case both .alpha.-R.sub.ij and .beta.-R.sub.ik are attached to the carbon atom to yield --C(.alpha.-R.sub.ij)(.beta.-.sub.ik)-. For example, when the bivalent variable R.sub.6, --C(.dbd.R.sub.6)-is defined to consist of two monovalent variable substituents, two monovalent variable substituents are .alpha.-R.sub.61 :.beta.-R.sub.62, ... .alpha.-R.sub.69 :.beta.-R.sub.610, etc, yielding --C(.alpha.-R.sub.61)(.beta.-R.sub.62)-, ... --C(.alpha.-R.sub.69)(.beta.-R.sub.610)-, etc. Likewise, for the bivalent variable R.sub.11, --C(.dbd.R.sub.11)-, two monovalent variable substituents are .alpha.-R.sub.111 :.beta.-R.sub.112. For a ring substituent for which separate .alpha. and .beta. orientations do not exist (e.g. due to the presence of a carbon carbon double bond in the ring), and for a substituent bonded to a carbon atom which is not part of a ring the above convention is still used, but the .alpha. and .beta. designations are omitted.

Just as a bivalent variable may be defined as two separate monovalent variable substituents, two separate monovalent variable substituents may be defined to be taken together to form a bivalent variable. For example, in the formula --C.sub.1 (R.sub.i)H--C.sub.2 (R.sub.j)H--(C.sub.1 and C.sub.2 define arbitrarily a first and second carbon atom, respectively) R.sub.i and R.sub.j may be defined to be taken together to form (1) a second bond between C.sub.1 and C.sub.2 or (2) a bivalent group such as oxa (--O--) and the formula thereby describes an epoxide. When R.sub.i and R.sub.j are taken together to form a more complex entity, such as the group --X--Y--, then the orientation of the entity is such that C.sub.1 in the above formula is bonded to X and C.sub.2 is bonded to Y. Thus, by convention the designation "... R.sub.i and R.sub.j are taken together to form --CH.sub.2 --CH.sub.2 --O--CO--..." means a lactone in which the carbonyl is bonded to C.sub.2. However, when designated "... R.sub.j and R.sub.i are taken together to form --CH.sub.2 --CH.sub.2 --O--CO-- the convention means a lactone in which the carbonyl is bonded to C.sub.1.

The carbon atom content of variable substituents is indicated in one of two ways. The first method uses a prefix to the entire name of the variable such as "C.sub.1 -C.sub.4 ", where both "1" and "4" are integers representing the minimum and maximum number of carbon atoms in the variable. The prefix is separated from the variable by a space. For example, "C.sub.1 -C.sub.4 alkyl" represents alkyl of 1 through 4 carbon atoms, (including isomeric forms thereof unless an express indication to the contrary is given). Whenever this single prefix is given, the prefix indicates the entire carbon atoms content of the variable being defined. Thus C2-C4 alkoxycarbonyl describes a group CH.sub.3 --(CH.sub.2).sub.n --O--CO-- where n is zero, one or 2 . By the second method the carbon atom content of only each portion of the definition is indicated separately by enclosing the "Ci-Cj" designation in parentheses and placing it immediately (no intervening space) before the portion of the definition being defined. By this optional convention (C1-C3)alkoxycarbonyl has the same meaning as C2-C4 alkoxycarbonyl because the "C1-C3" refers only to the carbon atom content of the alkoxy group. Similarly while both C2-C6 alkoxyalkyl and (C1-C3)alkoxy(C1-C3)alkyl define alkoxyalkyl groups containing from 2 to 6 carbon atoms, the two definitions differ since the former definition allows either the alkoxy or alkyl portion alone to contain 4 to 5 carbon atoms while the latter definition limits either of these groups to 3 carbon atoms.

When the claims contain a (cyclic) substituent, at the end of the phase naming/designating that particular substituent will be a notation in [brackets] or in (parentheses) which will correspond to the same name/designation in one of the CHARTS which will also set forth the chemical structural formula of that particular substituent.

EXAMPLE A

Conjugated Diene Formation Assay

The formation of conjugated dienes as assayed by Graughler, J. Neurochem., 44, 1282 (1985), Bucher, Fund. Applied Tox., 3, 222 (1983) and Tein. Arch. Biochem. Biophy., 216, 142 (1982) is a standard pharmacological laboratory procedure useful for identifying compounds which inhibit lipid peroxidation. Since lipid peroxidation is involved in the pathophysiology of central nervous system trauma, compounds which inhibit conjugated diene formation are useful in treating the conditions listed below.

Inhibition of conjugated diene formation as measured by any of the above procedures or the modified procedure below demonstrates usefulness in treating spinal trauma, mild and/or moderate to severe head injury, subarachnoid hemorrhage and subsequent cerebral vasospasm, ischemic (thromboembolic) stroke, muscular dystrophy, adriamycin cardiac toxicity, Parkinsonism, Alzheimer's disease, other degenerative neurological disorders, multiple sclerosis, organ damage during reperfusion after transplant, skin graft rejection, hemorrhagic, traumatic, or septic shock, severe burns, ARDS, allergic reactions, emphysema and post burn pulmonary complication. Further, an inhibition of conjugated diene formation also demonstrates usefulness in preventing damage following cardiopulmonary resuscitation, neurological or cardiovascular surgery and cardiac infarction.

While not necessary to demonstrate conjugated diene inhibition, the above assays have been modified as follows: rat brain synaptosomes are prepared according to the procedure described in J. Neurochem. 44, 1282 (1985). Synaptosomal suspension (10 .mu.l) is added to 1 ml of physiological (normal) saline containing 1% Lubrol PX (Sigma Chemical Co. St. Louis, Mo.), 100 .mu.M hydrogen peroxide and 100 .mu.M (or less) of the drug to be tested prepared in either absolute ethanol or water depending upon solubility. The reaction is started by the rapid addition of 200 .mu.M ferrous ammonium sulfate prepared in argon-purged water. The sample is rapidly mixed and the change in absorbance at 232 nm is followed in a Gilford Response Spectrophotometer equipped with a rapid sampler. Due to the rapidity of the reaction, rapid addition of the iron, rapid mixing and sampling are obligatory to the accuracy of the assay. For best results absorbance readings of one/sec should be started within 5 sec following the addition of iron. The initial linear rate of absorbance change during the first 30 sec of reaction are compared with the rate of a reaction containing all reagents except synaptosomes. The difference in rates is the rate of conjugated diene formation. Rates with drug are compared to rates obtained in the absence of drug and the % inhibition is calculated. A compound that inhibits conjugated diene formation by 50% or more is considered to be "active".

The compounds of Examples 2, 4, 5, 6B-8, 10-22, 24-28, 30-34, 36-41, 43-45, 47, 50-54, 58-76, 83, 84, 86, 93-99, 103-107, 111, 112 and 114-122 demonstrate such activity by inhibition of conjugated dienes.

The above in vitro test/assay is a standard pharmacological laboratory procedure for demonstrating compounds which are useful in treating the conditions listed above. Following the in vivo mouse head injury procedure of Hall, J. Neurosurg., 62, 882 (1985) compounds which statistically significantly (p<0.05) increase the 1 hr neurological recovery following head injury are considered preferred compounds for treating the above conditions, these are:

EXAMPLE B

Arachidonic Acid Antagonism Assay (AAAA)

The Arachidonic Acid Antagonism Assay (AAAA) as set forth in Thrombosis Res., 9, 67 (1976) is a standard laboratory procedure for demonstrating antagonism of the effects of arachidonic acid metabolites. Since these metabolites contribute to the pathological problems associated with stroke, spinal trauma and head injury, compounds which antagonize arachidonic acid are useful in treating stroke, spinal trauma and head injury. Compounds which significantly elevate the LD.sub.50 of arachidonic acid in animals are considered to be useful for the treatment of these conditions.

While not necessary to determine arachidonic acid antagonism, the above assay has been modified as follows: Charles River male CF-1 mice weighing 18-22 g are treated IV with the test compound dissolved in 1.0% Tween-80 and 0.1% hydrochloric acid in distilled water, 0.2 ml total volume. Fifteen minutes later sodium arachidonate (90% pure) in physiological (normal) saline is injected into the tail vein. The LD.sub.50 is measured using the Spearman-Karber method with a log dose interval of 0.05 (N=6). Compounds which elevate the LD.sub.50 outside of the 95% confidence interval of the control LD.sub.50 are considered to be "active".

The compounds of Examples 2, 4, 11-17, 19, 21, 22, 24, 25, 29, 41, 45, 47, 51, 53, 54, 57, 60, 62, 74, 75, 93 and 99-101 demonstrate arachidonic acid antagonism.

The following are test results in the Arachidonic Acid Antagonism Assay for the compounds identified:

EXAMPLE C

Malonyldialdehyde (MDA) Formation Assay

The MDA assays of Buege and Aust, Methods in Enzymology, Fleisher and Packer Editors, Academic Press, 1978, New York, Vol LII, p 302-310 and Kohn and Liversedge, J. Pharmacol. Exp. Ther. 82, 292 (1944) are standard pharmacological laboratory procedures for demonstrating the occurrence of lipid peroxidation by the formation of MDA. Since lipid peroxidation is involved in the pathophysiology of central nervous system trauma, compounds which inhibit MDA formation are useful in treating the conditions listed below.

MDA formation as measured by any of the above procedures or the modified procedure below demonstrates usefulness in treating spinal trauma, mild and/or moderate to severe head injury, subarachnoid hemorrhage and subsequent cerebral vasospasm, ischemic (thromboembolic) stroke, muscular dystrophy, adriamycin cardiac toxicity, Parkinsonism, Alzheimer's disease, other degenerative neurological disorders, multiple sclerosis, organ damage during reperfusion after transplant, skin graft rejection, hemorrhagic, traumatic and septic shock, severe burns, ARDS, allergic reactions, emphysema and post burn pulmonary complication. Further, MDA formation also demonstrates usefulness in preventing damage following cardiopulmonary resuscitation, neurological or cardiovascular surgery and cardiac infarction.

While not necessary to determine MDA formation, the above assays have been modified as follows: rat brain synaptosomes are prepared as described in the Example about the conjugated diene assay, except that the final wash of the synaptosomes and final suspension are in physiological (normal) saline in which the pH has been adjusted to 7.0. The synaptosomes are incubated for 10 min at 37.degree. in physiological (normal) saline pH 7.0 (total volume=100 ul) containing; 10 ul synaptosomal suspension, 10% DMSO plus or minus drug, 150 uM Fe.sup.+++ and 50 uM Fe++. The incubation is started by the rapid addition of iron to the otherwise complete reaction. The iron solutions are prepared fresh as ferric chloride and ferrous ammonium sulfate is argon-purged water. Following the 10 min incubation, the reaction is stopped by the addition of 500 ul ice-cold 12% trichloroacetic acid prepared in 0.5N hydrochloric acid. Water (300 ul) is then added along with 100 ul of freshly prepared thiobarbituric acid (3.3% in 0.5N sodium hydroxide) and 10 ul of 5 mM desferrioxamine. The sample is then heated in a boiling water bath for 20 minutes. The samples are cooled and centrifuged for 15 minutes at 1500.times.g and the absorbance of the supernatant fraction is read at 532 nm. The % inhibition of MDA formation is calculated by dividing the absorbance of sample containing drug by the absorbance of samples incubated without drug. Reaction blanks are samples incubated in the absence of iron. A compound that inhibits MDA formation by 50% or more at a concentration of 200 .mu.M or less is considered "active".

The compounds of Examples 17, 47, 49-52, 62, 67-71, 73-75, 83, 86, 95-97, 104, 107, 110, 111-113, 118, 120, 121, 125, 127 and 129 demonstrate such activity by inhibition of MDA formation.

The above in vitro test/assay is a standard pharmacological laboratory procedure for demonstrating compounds which are useful in treating the conditions listed above. Following the in vivo mouse head injury procedure of Hall, J. Neurosurg., 62, 882 (1985) compounds which statistically significantly (p<0.05) increase the 1 hr neurological recovery following head injury are considered preferred compounds for treating the above conditions, these are:

EXAMPLE D

AcylCoA:Cholesterol Acyltransferase (ACAT) Inhibition Assay

ACAT esterifies arterial cholesterol which is a key reaction in the development of atherosclerosis. The procedure of Bell, Can. J. Biochem. 60, 967 (1982) provides a standard procedure for demonstrating which compounds inhibit ACAT and therefore inhibit formation of esterified arterial cholesterol thereby preventing atherosclerosis. In the ACAT assay it is preferred to use Fu5AH cells, see Lipids 9, 526 (1974). According to this procedure, compounds which inhibit ACAT activity equal to, or greater than, that of chlorpromazine are considered "active".

The compounds of Examples 3, 17 and 18 are active in inhibiting ACAT.

The following are test results in the ACAT assay for the compounds identified:

EXAMPLE E

Antiatherosclerosis Screen in Susceptible to Experimental Atherosclerosis (SEA) Japanese Quail

Demonstration of antiatherosclerotic activity of a compound in SEA Japanese Quail is done by showing that the compound reduces the serum and arterial cholesterol in quail fed an atherogenic diet. This standard laboratory procedure for demonstrating a reduction in arterial and serum cholesterol in SEA Japanese quail has been described by Stevens in Atherosclerosis 56, 313 (1985). While not necessary, some minor modifications for extraction of cholesterol from the artery have been made. These are as follows: frozen arteries are homogenized in hexane/isopropanol (3/2) and the volume adjusted with Triton 100 solution (1.5% in hexane/isopropanol) to 7 ml. After standing 12 hr at 20.degree.-25.degree., the supernatant, obtained by low speed centrifugation is evaporated until dry and then the residue is suspended in 0.5 ml of 5% Triton 100 in isopropanol. This suspension is incubated for 10 min at 45.degree. to dissolve the material. This solution as well as the diluted serum samples are analyzed for cholesterol by standard clinical chemistry analyzer methods. According to the above procedure compounds which decrease serum or arterial cholesterol >30% are considered to be "active".

Compounds which reduce serum and arterial cholesterol and are useful in treating atherosclerosis and its complications; for example, reduction of serum cholesterol by drugs reduces the incidence of coronary heart disease, JAMA 251, 351 (1984) and JAMA 251, 365 (1984).

The compound of Example 3 demonstrates reduction of serum and arterial cholesterol.

EXAMPLE F

Inhibition of Interleukin-1

The inhibition of interleukin-1 induced T cell proliferation assay, Proc. Nat. Acad. Sci. USA, 78, 1133 (1981) is a standard laboratory procedure for demonstrating addition of interleukin-1 bioactivities. Since people with arthritis make excess interleukin 1, compounds which inhibit the activity of interleukin 1 are useful in the treatment of arthritis. According to this procedure compounds which inhibit the activity of interleukin 1 greater that 30% at 10.sup.-6 M are considered to be "active".

The compounds of Examples 21, 37, 47, 83, 94, 96, 94, 96, 97, 101, 105 and 120 demonstrate inhibition of interleukin 1.

Inhibition of Mucous Secretion

The inhibition of mucous secretion assay of Johnson Int. Arch. of Allergy and Applied Immunology 75, 97 (1984) is a standard pharmacological laboratory procedure for demonstrating inhibition of mucous secretions and therefore usefulness in preventing and/or treating mucous secretions, asthma, inflammatory lung diseases, bronchitis, allergic reactions and ARDS. According to this procedure compounds which inhibit or block enhancement of induced mucous secretions when tested are considered to be "active".

The compounds of Examples 2, 4, 16, 18, 83 and 105 demonstrate such activity.

The test results disclose that the compounds of Examples 2, 83 and 105 are the preferred mucous inhibitors.

EXAMPLE H

Asthma Test in Ovalbumin Sensitized Guinea Pigs

The ovalbumin sensitized guinea pig test, Brit. J. Pharm. 78, 67 (1983) is a standard laboratory procedure for demonstrating inhibition of bronchoconstriction and therefore use in treating/preventing asthma. While not necessary the above test has been modified as follows. Male guinea pigs (500-700 g at the time of antigen challenge) are sensitized by IM injection of ovalbumin (5%, 0.35 ml) into each hind limb and repeated 6 days later. Five weeks after the initial injection of ovalbumin, the animals are anesthetized with urethane (1.5 g/kg intraperitoneally), the trachea cannulated and the lungs ventilated at constant volume using a Harvard Apparatus Rodent Respirator. Tracheal pressure is measured from a side-arm of the tracheal cannula via a Statham P23AC pressure transducer of a furness control micromanometer. The chest is opened along the mid-line. Bronchoconstriction is measured as the absolute increase in transpulmonary pressure in cm water with respect to the atmosphere. Blood pressure is recorded using a Statham P23Db pressure transducer vial a catheter inserted into a carotid artery. Heart rate is derived from the blood pressure signal using a Grass 7P4F tachograph. A jugular vein is catheterized for injection of drugs and antigen. The animals are pretreated with the following: indomethacin (10 mg/kg, 15 min prior to antigen), pyrilamine maleate (2 mg/kg, 10/11 min before antigen), and propranolol (0.25 mg/kg, 5 min prior to antigen). Antigen challenge consists of ovalbumin (0.3 mg/kg) given IV.

The compounds to be tested are administered by either IV (compound precedes the antigen challenge by four minutes), orally (fasted animals are dosed at either 2 or 4 hr prior to challenge) or by aerosol (the compound is nebulized thru the Harvard respirator and directly into the tracheal cannula 180 sec four min prior to the IV antigen challenge). Vehicles include IV (saline), oral (emulphor or 0.1% Tween 80) or for aerosol (DMSO).

The antigen provocation produces a slowly developing bronchoconstriction which lasts at least 15 min. The percent inhibition at various times points after antigen challenge compares the test compound to control animals (vehicle only). According to this procedure compounds which give 50% or greater inhibition at 10 mg/kg are considered to be "active".

EXAMPLE I

Inhibition of Tumor Growth

The fertile egg or chick embryo assay of Folkman, Science 221, 719 (1983) is the standard pharmacological laboratory procedure for demonstrating inhibition of angiogenesis, and therefore of tumor growth [Folkman, in Advances in Cancer Research, G. Klein and S. Weinhouse, ed., 43, 175 (1985)]. According to this procedure compounds which are considered to be "active" (i.e. antiangiogenic) give an avascular zone of 4 mm or greater in some embryos when tested at 50 .mu.g/10 .mu.l in the presence of 50 .mu.g/10.mu. of heparin.

The compounds of Examples 2-5, 6B, 8-10, 12-18, 20, 21, 24, 26-30, 32, 33, 34, 36, 37, 39-41, 43-48, 51-55, 63, 64, 83, 86, 97, 99, 104 and 105 demonstrate inhibition of angiogenesis.
